' 22 Claims. (Cl.,70-'108) invention relates to key-controlled locks and more particularly to so-called padlocks.

One of the objects of this invention is to provide a thoroughly practical, reliable, and dependable padlock construction adapted dependably to containspare parts for replacement or repair. Another object is toprovide a construction of this character in which dependable and reliable control over such spare parts is achieved.

10 Another-object is to provide a construction of the above character which will retain an adequate supply of spare parts and permit access thereto only when unlocked. Another object is to provide a construction of the above character which 15 may bereadily disassembled for purposes of repair when unlocked but which cannot be disassembled when locked, Other objects will be in part obvious'or in part pointed out hereinafter.

The invention accordingly consists in the fea- 20 tures of construction, combinations of elements, and arrangementsof parts as will be exemplified i in the structure tobe hereinafter described and the scope of the application of which will be indicated in the following claims.

uliigure is a front elevation on a smaller scale, certain parts being broken away and other 45 parts shown in section, of a padlock construction showing one form of key-controlled locking means; that may be employed for coaction with the padlock shackle and related parts.

Similar reference characters refer to simila 5 parts throughout the; several views of the draw- As conducive to a clearer understanding of certain features of this invention, it might here e noted that one. of: the most aggravating and 55 troublesome disadvantages met with in padlock constructions heretofore known is that, when a part of the mechanism breaks or requires replace,- merit; greatdificultyand delay are experienced either-obtaining such spare parts or replace.- ments or inspecially making them up. For ex- 5 ample, the key plug employed in padlocks may be of the type utilizing pin tumblers and springs for the'latter or it may be of any other suitable type, such as the type employingso-called wafer tumblers with springs for the latter. These 10 tumblers and springs and related parts are. very small and are diflicult to duplicate. Also many padlocks now in common use may be easily disassembled while in locked position. thus being entirely inadequate protection against undesired entry or the like. Many of these padlocks when disassembled for purposes of repair even when unlocked are so severely damaged thereby that theyare beyond repair. One of the dominant aims of this invention is to provide a dependable padlock construction embodying adequate spare parts so as to avoid such difficulties and disadl vantagesas have just been mentioned.

Referring now to the drawing and more particularly toFigure l, I have shown a padlock constructionwhich may be of any suitable or desired type or construction; illustratively, it comprises a casing or body ID having pivotally and slidablymounted therein a U-shaped locking member 11 whose one shank I 2 is slidably and pivotally mounted in a suitable channel or guideway I 3 extending vertically at one end of the casing l0 and whose left-hand shank I4 is adapted, when swung into position and the member ll pressed downwardly, to enter a channel or hole I5. The body ID has rotatably mounted therein a key plugindicated. at It for operation by way of a key insertable at the bottom end of the body I U. The key plug Hi may be constructed to coactwith the body or casing H) in any suitable manner, as by pin tumblers l8 and- H8 and springs t9- (Figure 3) or as by the wafer type of tumblers 20 and springs 2| (Figure 4), as will be understood by those skilled in the art, and any suitable means, heretofore known, may be employed: for causing the key plugl6- to prevent or permit the withdrawal of the locking member I l upwardly or its rotation about the one shank l2 thereof. For example, the vertical shanks l 2 and It may have notches la and Ma, respectively, with which may coactmembers within the body I9 under the control of the key plug it and its associated key (not shown). I

.InFigurefl I have shown, by way of illustration, how these parts may be arranged and constructed and, turning to Figure '7, the key'plug I6 is proshown in Figure 7, I have shown two respectively ,1

the latter are coacting casing tumblers H8; 7

spring-pressed toward the right, as viewed in Figure 7, by their springs I 9. I

Accordingly, rotation of the key plug I6 isiper-'- mitted or prevented accordingasthe proper keyis inserted in the key slot or not. And as above noted, the keyplug I 6 controls suitable members,

shown in Figure 7 at 5I and 52 for coaction with the notches Ma and I2a in the shanks of the shackle Ii. Any suitable means, diagrammatically indicated at 53 in Figure 7, may be employed to bring aboutthe desired coaction of the members 5I, 52 with the key plug I6 and the shackle I.I, various such means being well known in the ,a'rtJ On the top wall 22 of the casing I and integrall'y formed therewith is a four-walled chamber 23made up of the left end wall, the right end wall 25, and the spaced side walls 26 and 21, the latter projecting upwardly beyond the former. Thebottom of the chamber 23 may be formed in the same plane with the plane ofthe top wall 22 of the casing II], or it may extend downwardly into the casing or body I0, if desired. 7

The length of the chamber 23in a direction I from the left to the right is slightly less than the spacing between the shanks I2.I4 of the looking member I I, and the'width of the chamber 23, that is, thefspacing of the side walls 26-21, may be commensurate with the thickness of the body ID. ',The upwardly extended portions of the side walls 26-21 are undercut, as at 26c and 21a,

' respectively, to form guideways whose base portions are in the plane of the top faces of the end walls 25-45. Into these slideways is received a closure member 28' (Figure 2) having its side edges beveled as at 28a and 28b to be snugly and relatively "tightly and slightly received in the undercut guideways 2611-2111, respectively, closure member 28 being of a length commensurate with the outside dimension or. length of and springs like those: shown in Figures -3 or 4,

depending upon'the key plug construction that is employed. 7 Under certain circumstances, chamber 23 may be bottomless thus opening into the interior of casing I I}. Of course, when so constructed, the

' casing cannot be used forstorage' of spare parts but is-a convenient means of gaining access 'to the interior of the casing for purposes of. disassembly or repair. a I V The closure 28 is forced into place, being fric-' tionally held-against being'dislodged'but being provided with a depression 280 in its top face to permit itto'be moved: with the fingernail or withaztooh F V threaded into hole 39 to hold the cover plate in the When the chamber 23 is closed by the member 26, thus to enclose the spare parts, access to V the latter can be gained only'with the aid of V the key (not shown) which is necessary to release the locking member I I, thus to permit it 130 5 be moved or swung away from the end wall 24 and thus to permit the member 28 to be withdrawn to gain access to the spare parts.

Thus the construction carries'with itrepair' parts and, moreover, does so'in' a manner asto prevent unauthorized tampering therewith.

Turning now to Figure 5, I have shown a padlock generally indicated at 29 which, like the padlock shown in Figure 1, may be of any suitable construction having a casing 36 and a U- shaped lockingmember generally indicated at 3 I. Member 3I is free to slide longitudinally with respect to casing 3Ilthus having a short end 33 V and a long end 34; 'End 34 is permanently seated within the casing 30 and the member 3| may pivot thereabout as an axis after, being. moved .into the open position shown in- Figure 6.

. As moreclearly shown in Figure. 6, I provide a channel 35 formed in the sideof casing adjathe parts described above to be stored in cham- 5 for locking member 3I in-its closedjposition are located. A hole 39 in the bottom oi channel is, thus formed therein and preferably retains a pin for holding in operative position certain of the interior parts of the lock, as, for example, the lock cylinder (not shown). K'Ihus with; a lock of this construction when channel- 35 is. exposed as shown in Figure '6 andthelock is turned so that the bottom of channel 35 is uppermost, the 7 pin in hole 39 falls out as do the locki ng1bo1ts,

thus to afford a quick disassembly of the entire mechanism. Y 7

When the member 3| isin itslocke'd. position (Figure '5), end portion '33: extends through a suitable hole 46 in casing 36 as shown in Figure 6,

A suitable recess 4| surrounds hole w 'toprovide a shoulder lIa. Thus a coverf42 having beveled walls corresponding .towalls 35a and 35b is.pro- I vided which may slide into channel 35.,having beenplaced in endwise relationth'ereto. Cover' 42 has a right angle extension43 which fits within 5.5 recess II and has a hole '44 extending there'- through in registry with hole 40; A screw 45 extends through a hole 46 in cover'plate42iand is closed position shown-in Figure 5; 1"

Suitably formed upon member 3| substantially adjacent end portion 33'are a pair-of lip'portions 41 and 48. Thus whenmember 3I is in its closed 7 and locked position (Figure '5), lips 41 and 48 a abut against right angle projection 4330f cover 6.5

the member 3| is in locked position. 7 However,

when repair is desirable, the lock may be opened, thus swinging end portion 33 away from i'i'gh't angleprojection "43 (Figure 6), and, upon'the removal of screw 45, cover plate '42 may "be"r- 715= moved to expose the interior of the lock. As pointedbut above, the spare parts 3? are then readily; accessible and also the various parts of the'lock may be disassembled by the simple process of turning the casing upside down. Of course it should be understood that this construction might be applied to a lock wherein disassembly might be achieved in some other manner after the removal of cover plate 42 without departing from the scope of this invention.

Accordingly, I have provided a thoroughly practical and efiicient construction in which the several objects hereinabove referred to are efficiently and'successfully accomplished.

As many possible embodiments may be made of the above invention and as many changes might be made inthe embodiment above set forth, it is to be understood that all matter hereinbefore set forth, or shown in the accompanying'drawing, is .to be interpreted as illustrative and not in a limiting sense.
